On-Demand XML Data Broadcast in Wireless Computing Environments
In mobile wireless systems data on air can be accessed by a large number of mobile users. Many of these applications including wireless internets and traffic information systems are pull-based, that is, they respond to on-demand user requests. In this paper, we study the scheduling and indexing techniques of XML on-demand broadcasting. Our main contributions are 1) pre-processing the original XML documents by pruning the superfluous parts before broadcast scheduling; 2) indexing XML documents in the broadcast disk using DataGuides structure. Experiments show our approaches reduce both access time and tuning time significantly.
